This edition presents for the first time the original full-size laser master of Richard CookÕs 1995 LTBA 18.2 monograph. In this typographically complex and copiously illustrated study, the original signification of the Chinese _ chŽn pictogram is demonstrated from graphic, semantic, and phonological perspectives. On the basis of an examination of the extant Chinese material from all historical periods, it is shown that the _ chŽn sign is in fact a representation of a scorpion in striking position as seen in profile. It is shown that this representation bears directly upon the once vigorous traditions relating to the ancient equinoctial position of the star Antares in the Breast of the Celestial Scorpion. And though certain stellar concepts betray the likelihood of an early (pre-OBI) Sino-Mesopotamian relation (stimulus diffusion), these concepts nevertheless took peculiar Chinese form, such that it is possible to demonstrate the cognacy of Chinese _ chŽn and ÔscorpionÕ words in Sino-Tibetan.
